What is the Speed of Gravity?
Posted: Tue Oct 06, 2020 6:38 am
I want to challenge the reasoning used by Wal Thornhill and Bishop Nicholas Sykes asserting the speed of gravity must be nearly instantaneous in the ThunderboltsProject video "What is the Speed of Gravity?". I believe the reasoning used in the Sykes diagram may be incorrect. This is my first post and I have not been able to find and read the Oct 22 2016 Thunderbolts forum post that Sykes refers to. If anyone can help me locate that I would be grateful.
I am an enthusiastic supporter of Electric Universe concepts. The following statements outline how I understand the speed of gravity in some circumstances. If this isn't clear enough to be convincing, I can post an alternative argument with some diagrams. If I'm wrong I hope someone can explain why.
I am assuming the Sun rotates with respect to the Earth.
*If the speed of gravity is instantaneous then the Sun has rotated for 0 minutes by the time the Earth experiences it's gravitational pull.
*If the speed of gravity is C then the Sun has rotated for approx 8 minutes by the time the Earth experiences it's gravitational pull.
*If the speed of gravity is C/2 then the Sun has rotated for approx 8*2 minutes by the time the Earth experiences it's gravitational pull.
*All such cases are equivalent because the Sun's centre of gravity is in the same position relative to the Earth. The only change is the realtime rotational position of the Sun due to the gravitational delay. The Earth can thus have a stable orbit for *any speed of gravity*.
I believe this holds for any binary star system because the realtime position of each star is irrelevant if there is any delay in their gravitational attraction. This also holds if the Earth's orbit was elliptical.
